Drug-related visual blurring: findings from the U.S. Food and Drug Administration Adverse Event Reporting System database
Article
Author: Chen, Lin ; Liu, Zuguo ; Wu, Shi-Nan ; Hu, Jiaoyue ; Sun, Le ; Guan, Wen-Ying ; Huang, Caihong ; Chen, Xiao-Dong ; Liu, Qian-Ting ; Kang, Jia-Yu
BACKGROUND:
Visual blurring is one of the most common symptoms in ophthalmology, and one of the important causes of secondary visual blurring is drug-related. This study assesses the risk of drug-related visual blurring using a large real-world database.
METHODS:
We analyzed adverse event reports from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database between January 2004 and September 2024. Disproportionality analysis algorithm were used. Drugs related with positive signals for visual blurring were categorized, and the risk levels, number of reports, and drug-induced onset times were quantified.
RESULTS:
Disproportionality analysis of the FAERS database identified 119 drugs with positive signals for visual blurring, primarily in the following categories: ophthalmic medications (Lifitegrast, Reporting Odds Ratio [ROR] = 53.24; 95 % Confidence Interval [CI]: 49.19-57.61), endocrine medications (Semaglutide, ROR = 3.26 [2.84-3.75]), nervous system medications (Pregabalin, ROR = 4.15 [3.93-4.37]), oncology medications (Encorafenib, ROR = 5.38 [4.37-6.62]), antimuscarinic medications (Fesoterodine, ROR = 6.77 [5.08-9.03]), and other medications (Dupilumab, ROR = 8.39 [8.16-8.64]). The top three drugs associated with the highest incidence of blurred vision as an adverse event are lifitegrast, oxymetazoline, and olopatadine. Antimuscarinic Medications had the shortest drug-induced onset time. Women (63.87 %) and middle-aged to elderly individuals [Age (mean ± standard deviation): 53.59 ± 18.79] were the main populations affected by drug-related visual blurring.
CONCLUSION:
Preventing drug-related vision issues is vital. Early risk assessment and intervention with personalized medication can reduce side effects, ensure safety, and improve quality of life.

Ranking the efficacy of topical treatments for ocular allergy: A network meta-analysis of current evidence
Review
Author: Krungkraipetch, Dechathorn ; Tansavadi, Taweelarp ; Krungkraipetch, Luksanaporn
PURPOSE:
To evaluate and rank the comparative effectiveness of topical treatments for different types of ocular allergies through a systematic review and network meta-analysis.
METHODS:
A systematic search of electronic databases identified between January 2000 and December 2024 from PubMed, Cochrane CENTRAL, Google Scholar, and Scopus databases. Study Selection; randomized controlled trials assessing topical treatments for ocular allergy, including antihistamines, corticosteroids, immunomodulators, and combination therapies. Data Extraction and Synthesis; data were independently extracted and analyzed following PRISMA guidelines. Direct and indirect comparisons were evaluated using network meta-analysis, and SUCRA rankings assessed relative efficacy. Main Outcomes and Measures; reduction in ocular itching, redness, and inflammation. PROSPERO Registration number: CRD42025634572.
RESULTS:
Olopatadine 0.1 % demonstrated highest efficacy in seasonal and perennial allergic conjunctivitis (SUCRA 0.88 and 0.85, respectively), while Tacrolimus 0.1 % showed superior effectiveness in vernal and atopic keratoconjunctivitis (SUCRA 0.92 and 0.89, respectively). Overall treatment effect was significant (OR = 6.95, 95 % CI: 6.24-7.75) with moderate heterogeneity (I2 = 50.8 %). Subgroup analysis revealed consistent efficacy across different types of allergic conjunctivitis, with seasonal allergic conjunctivitis showing the highest cumulative ranking probability (89.0 %).
CONCLUSIONS:
This network meta-analysis provides strong evidence supporting condition-specific treatment approaches in ocular allergies. Newer antihistamines, particularly Olopatadine, are most effective for mild-moderate conditions, while immunomodulators, especially Tacrolimus, show superior efficacy in severe cases. These findings provide clear evidence-based hierarchies for clinical decision-making in the management of different types of allergic conjunctivitis.

Association between congenital Zika syndrome and hospitalizations during early childhood: a nationwide cohort study
Article
Author: Teixeira, Maria Gloria ; Paixão, Enny S ; Barreto, Mauricio L ; Tedde, João Guilherme G ; Costa, Maria da Conceição ; Silva, Thiago Cerqueira ; Cardim, Luciana ; Rodrigues, Laura ; Brickley, Elizabeth B
OBJECTIVES:
Congenital Zika Syndrome (CZS) has been linked to a wide spectrum of abnormalities. However, differences in hospitalization patterns between children with and without CZS have not yet been investigated.
METHODS:
We compared rates of hospital admissions for all and specific diseases, proportions of admission causes, and total length of hospital stay (LOS) between children with CZS and those without the syndrome. Adjusted incidence rate ratios (aIRR) and aLOS were estimated using negative binomial regression.
RESULTS:
Compared to those without CZS, the aIRR for all-cause hospitalizations in the CZS group ranged from 3.77 (95%CI: 3.47-4.06) in the neonatal period to 7.76 (95%CI: 6.91-8.61) at ages 2-4 years. Similar trends were observed for specific causes of admissions. Most admissions in the CZS group related to congenital malformations, neurological, respiratory and infectious diseases. aLOS ranged from 16.0 days [95%CI: 13.2-19.5] to 19.9 days among CZS patients and 6.0 days [95%CI: 5.9-6.2] to 9.3 days [95%CI: 9.3-9.4] for patients without the syndrome.
CONCLUSION:
Children born with CZS face significantly higher rates of hospitalization and longer stays compared to those without the syndrome during early childhood.
